A fully automatic intelligent temperature controller

Abstract

The present invention belongs to the technical field of industrial thermostats, and specifically relates to a fully automatic intelligent thermostat, which includes a wiring base box and an integrated top box, wherein the wiring base box includes a bottom cover; the integrated top box includes a top cover, on which a temperature acquisition board is mounted; and movable wiring terminals and fixed wiring terminals are mounted within the bottom cover, the movable wiring terminals and fixed wiring terminals being respectively connected to the temperature acquisition board. When the appliance short-circuits, a stepper motor drives the turntable and slider to rotate, the insulating rod disengages the movable contact, causing the movable contact to disconnect from the fixed contact under the action of a spring. The electromagnet is then reversely energized, causing the electromagnet to repel the permanent magnet on the cylinder, separating the slider from the turntable. When the circuit temperature drops, the stepper motor drives the turntable to rotate via a belt. Since the slider is separated from the turntable, the thermostat is disconnected when the turntable rotates, preventing the thermostat from automatically connecting after the temperature drops, causing secondary damage to the appliance.

Description

Technical Field

[0001] The invention belongs to the technical field of industrial temperature controllers, and in particular relates to a fully automatic intelligent temperature controller. Background Art

[0002] A thermostat is a control element that turns on or off according to the temperature changes in the working environment. It is often used on industrial equipment to start protection.

[0003] Conventional thermostats can automatically open and close circuits. For example, in the invention patented under publication number CN114779852A, the thermostat automatically disconnects when it senses the temperature exceeds a set point, and automatically reconnects when the temperature drops. However, temperature fluctuations can be caused by a variety of factors, primarily circuit overload and short circuit.

[0004] When a circuit is overloaded, the current in the circuit will increase compared to normal operation. According to Joule's law, as the current slowly increases, the heat generated per unit time will gradually increase. At this time, the thermostat can disconnect the circuit for protection. When it stops being used and the temperature drops, the thermostat will automatically restore the circuit connection.

[0005] When a short circuit occurs, the resistance of the circuit remains essentially unchanged, but the current increases dramatically. Joule's law states that, given a constant resistance, a sharp increase in current generates a significant amount of heat, causing the circuit temperature to rise sharply. If the user fails to correct the problem promptly, the circuit temperature may drop and the thermostat may automatically connect the circuit, causing secondary damage to the appliance.

[0008] As a further optimization or improvement of this solution, a slot is installed in the power box, the fixed contact is installed on the slot, and a spring is installed between the moving contact and the power box.

[0009] As a further optimization or improvement of this solution, a cover plate is installed on the top cover, and a temperature display and a communication interface are installed on the top cover; the temperature panel of the integrated top box monitors the line temperature in real time. If the line temperature rises suddenly, it can be determined that the appliance is short-circuited; if the line temperature rises slowly, it can be determined that the appliance is overloaded.

[0010] As a further optimization or improvement of this solution, a resettable plunger is slidably installed in the air cylinder, a roller is installed at one end of the plunger close to the turntable, and a convex platform is installed on the outer wall of the turntable shaft, and the convex platform cooperates with the roller.

[0013] As a further optimization or improvement of this solution, the bottom cover has screw holes arranged diagonally.

[0014] Beneficial effects of the present invention:

[0015] (1) When the appliance is overloaded, the stepper motor drives the turntable and slider to rotate through the belt, so that the insulating rod is separated from the moving contact, and the moving contact is disconnected from the fixed contact under the action of the spring; when the circuit temperature drops, the controller on the integrated top box controls the stepper motor to operate, so that the stepper motor drives the turntable and slider to rotate through the belt, so that the slider drives the insulating rod to push the moving contact to connect with the fixed contact, so that the temperature controller is connected;

[0016] When the electrical appliance is short-circuited, the stepper motor drives the turntable and the slider to rotate through the belt, causing the insulating rod to separate from the moving contact, and the moving contact to be disconnected from the fixed contact under the action of the spring. Then the electromagnet is energized in the reverse direction, causing the electromagnet to repel the permanent magnet on the air cylinder. At this time, the air cylinder drives the pressure block away from the outer wall of the turntable, separating the slider from the turntable; when the line temperature drops, the stepper motor drives the turntable to rotate through the belt. Since the slider is separated from the turntable, the thermostat is in the disconnected state when the turntable rotates, avoiding the thermostat automatically connecting after the temperature drops, causing secondary damage to the electrical appliance.

[0017] (2) In the present invention, when the electrical appliance is short-circuited, the slider is separated from the turntable, and the air hole of the air cylinder is directed toward the fixed contact and the moving contact. At this time, when the stepper motor drives the turntable to rotate through the belt, the convex platform on the turntable will continuously press the roller, so that the roller drives the plunger to push back and forth into the air cylinder, blowing the gas inside the air cylinder toward the fixed contact and the moving contact, accelerating the lowering of the fixed contact and the moving contact, and preventing the short-circuit high temperature of the fixed contact and the moving contact from being transmitted to the internal components of the fixed wiring terminal and the moving wiring terminal, causing damage to the internal electrical components and circuit boards of the fixed wiring terminal and the moving wiring terminal.

DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0030] See also Figures 1-8A fully automatic intelligent temperature controller includes a wiring base box 1 and an integrated top box 2, which are snap-connected. The wiring base box 1 includes a bottom cover 101, on which a current transformer wire hole 103 is installed; the integrated top box 2 includes a top cover 201, on which a temperature collection board 202 is installed; a movable wiring terminal 5 and a fixed wiring terminal 9 are installed in the bottom cover 101, and the movable wiring terminal 5 and the fixed wiring terminal 9 are respectively connected to the temperature collection board 202, a fixed contact 4 is installed on the fixed wiring terminal 9, and a movable contact 6 is installed on the movable wiring terminal 5; an opening and closing component 8 is installed in the bottom cover 101, and the opening and closing component 8 includes a power box 801, a stepping motor 803 and a slide 806, and the slide 806 and the stepping motor 803 are respectively fixedly installed in the power box 801. The stepping motor 803 drives the turntable 802 to rotate through the belt 804. A slider 805 is slidably installed on the turntable 802. The slider 805 is connected to one end of the insulating rod 810 through the connecting column 811. The other end of the insulating rod 810 slides with the slide groove 806 through the slide rod 809. The insulating rod 810 pushes the moving contact 6 to connect with the fixed contact 4 to connect the circuit; a pressure block 815 is installed on the slider 805, and a rotating sleeve 814 is rotatably installed on the side wall of the rotating shaft of the turntable 802. An electromagnet 813 is installed on the side wall of the rotating shaft of the turntable 802. The pressure block 815 is connected to the air cylinder 816. The air cylinder 816 slides with the rotating sleeve 814. A permanent magnet 819 is installed on the end of the air cylinder 816 close to the turntable 802. The permanent magnet 819 and the electromagnet 813 attract each other, and the pressure block 815 presses the outer wall of the turntable 802.

[0031] Specifically, a cover plate 206 is installed on the top cover 201, and a temperature display 204 and a communication interface 205 are installed on the top cover 201; the temperature panel on the integrated top box 2 monitors the circuit temperature in real time. If the circuit temperature rises suddenly, it can be determined that the electrical appliance is short-circuited; if the circuit temperature rises slowly, it can be determined that the electrical appliance is overloaded.

[0032] It's important to note that when an appliance is overloaded, the current in the circuit will increase slightly compared to normal operation, but this increase is relatively slow. Because overloads typically increase gradually, the increase in current is also gradual. According to Joule's law, as the current slowly increases, the heat generated per unit time also gradually increases. Although circuits have a certain heat dissipation capacity, over time, the heat generated gradually accumulates, causing the circuit temperature to slowly rise.

[0033] When a short circuit occurs, the circuit's resistance remains essentially unchanged, but the current increases dramatically. This is because the current no longer flows through the normal electrical load, but instead flows directly back through low-resistance paths such as wires, causing the current to instantly become very high. Joule's law states that, given a constant resistance, a sudden increase in current generates a significant amount of heat, causing the circuit temperature to rise sharply.

[0034] Based on this, the present invention monitors the circuit temperature in real time through the temperature panel on the integrated top box 2. If the circuit temperature rises suddenly, it can be determined that the appliance is short-circuited; if the circuit temperature rises slowly, it can be determined that the appliance is overloaded.

[0035] When the appliance is overloaded, the stepper motor 803 drives the turntable 802 and the slider 805 to rotate through the belt 804, so that the insulating rod 810 disengages the moving contact 6, and the moving contact 6 is disconnected from the fixed contact 4 under the action of the spring 7; when the line temperature drops, the controller on the integrated top box 2 controls the stepper motor 803 to operate, so that the stepper motor 803 drives the turntable 802 and the slider 805 to rotate through the belt 804, so that the slider 805 drives the insulating rod 810 to push the moving contact 6 to connect with the fixed contact 4, so that the temperature controller is connected.

[0036] When the electrical appliance is short-circuited, the stepper motor 803 drives the turntable 802 and the slider 805 to rotate through the belt 804, causing the insulating rod 810 to disengage from the moving contact 6, and the moving contact 6 is disconnected from the fixed contact 4 under the action of the spring 7. Then the electromagnet 813 is energized in the reverse direction, causing the electromagnet 813 to repel the permanent magnet 819 on the air cylinder 816. At this time, the air cylinder 816 drives the pressure block 815 away from the outer wall of the turntable 802, so that the slider 805 is separated from the turntable 802; when the line temperature drops, the stepper motor 803 drives the turntable 802 to rotate through the belt 804. Since the slider 805 is separated from the turntable 802, during the rotation of the turntable 802, the turntable 802 cannot drive the insulating rod 810 to close the moving contact 6 and the fixed contact 4 through the slider 805, so that the thermostat is in the disconnected state, avoiding the thermostat automatically connecting after the temperature drops, causing secondary damage to the electrical appliance.

[0037] Specifically, the present invention realizes physical isolation and active heat dissipation after a short circuit through electromechanical coordinated control, which specifically includes:

[0038] Two-level disconnection mechanism:

[0039] Level 1 disconnection: When the temperature sensor detects a sudden temperature rise (slope ≥ 10°C / s), the stepper motor 803 drives the turntable 802 to rotate, the slider 805 disengages from the moving contact 6 through the insulating rod 810, and the spring 7 resets to force the moving / fixed contacts 4 to separate.

[0040] Secondary locking: The electromagnet 813 is energized in the reverse direction, generating a repulsive force (magnetic induction intensity ≥ 0.5T) with the permanent magnet 819 at the end of the air cylinder 816, pushing the air cylinder 816 to move laterally, causing the slider 805 to disengage from the turntable 802, ensuring that the turntable 802 cannot drive the slider 805 to reset when it rotates, completely blocking the automatic reconnection path.

[0041] Pneumatic active cooling:

[0042] The air cylinder 816 has a built-in plunger 817-roller 818 mechanism. When the turntable 802 rotates, the convex platform 812 periodically squeezes the roller 818, driving the plunger 817 to reciprocate (frequency ≥ 5Hz), pressurizing the external air and then spraying it directionally onto the contact surface. The air flow speed is ≥ 3m / s, and the contact cooling rate is increased to 15℃ / s (traditional natural heat dissipation is only 2℃ / s).

[0043] See also Figure 4-Figure 5 A card slot 807 is installed in the power box 801, the fixed contact 4 is installed on the card slot 807, and a spring 7 is installed between the moving contact 6 and the power box 801.

[0044] It should be noted that, in the initial state, the fixed contact 4 is fixed in the mounting slot 807, and the moving contact 6 is disconnected from the fixed contact 4, that is, the thermostat is in the disconnected state. If the circuit needs to be connected, refer to Figure 9 , electromagnet 813 is energized, electromagnet 813 attracts permanent magnet 819 on cylinder 816, so that permanent magnet 819 fits electromagnet 813, roller 818 and plunger 817 are pressed into cylinder 816, see Figure 8 At this point, permanent magnet 819 drives air cylinder 816 into rotating sleeve 814. Simultaneously, air cylinder 816 drives pressure block 815 to press against the outer wall of turntable 802, securing slider 805 to turntable 802. As stepper motor 803 rotates turntable 802 via belt 804, turntable 802 drives slider 805 to rotate synchronously. Slider 805 drives insulating rod 810, pushing movable contact 6 into contact with fixed contact 4, thus connecting the thermostat.

[0045] See also Figure 7-Figure 9 A resettable plunger 817 is slidably installed in the air cylinder 816, and a roller 818 is installed at one end of the plunger 817 close to the turntable 802. A convex platform 812 is installed on the outer wall of the rotating shaft of the turntable 802, and the convex platform 812 cooperates with the roller 818.

[0046] It should be noted that an annular groove 808 is provided on the rotating disk 802 , and the slider 805 is in sliding engagement with the annular groove 808 .

[0047] It should be noted that when an electrical appliance is short-circuited, the temperature of the fixed contact 4 and the moving contact 6 rises suddenly. Even if the fixed contact 4 and the moving contact 6 are disconnected in time, the high temperature of the fixed contact 4 and the moving contact 6 will still be transmitted to the internal components of the fixed terminal 9 and the moving terminal 5, causing damage to the internal electrical components and circuit boards of the fixed terminal 9 and the moving terminal 5.

[0048] Based on this, when the electrical appliance is short-circuited, the slider 805 of the present invention separates from the turntable 802, and at the same time, the air hole of the air cylinder 816 faces the fixed contact 4 and the moving contact 6. At this time, when the stepper motor 803 drives the turntable 802 to rotate through the belt 804, the convex platform 812 on the turntable 802 will continuously press the roller 818, so that the roller 818 drives the plunger 817 to push back and forth into the air cylinder 816, blowing the gas inside the air cylinder 816 toward the fixed contact 4 and the moving contact 6, accelerating the lowering of the fixed contact 4 and the moving contact 6, and preventing the short-circuit high temperature of the fixed contact 4 and the moving contact 6 from being conducted to the internal components of the fixed terminal 9 and the moving terminal 5, causing damage to the internal electrical components and circuit boards of the fixed terminal 9 and the moving terminal 5.

[0049] See also Figure 1-Figure 3 The bottom cover 101 is provided with a guide rail groove 104 , a buckle 105 is installed on the bottom cover 101 , and a bayonet 207 is provided on the top cover 201 , and the buckle 105 is engaged with the bayonet 207 .

[0050] Specifically, the bottom cover 101 is provided with screw holes 3 arranged diagonally.

[0051] Specifically, the bottom cover 101 is provided with bottom heat dissipation holes 102 , and the top cover 201 is provided with top heat dissipation holes 203 .

[0052] It should be noted that the wiring bottom box 1 is used to control the line connection; the integrated top box 2 integrates the temperature detection panel, the data processing panel, the wireless panel and the control panel, that is, the function of the integrated top box 2 is mainly used to detect the temperature change of the electrical circuit, and send the temperature change signal through the wireless panel. At the same time, the temperature change signal is transmitted to the control panel after data processing, and the control panel controls the power-on state of the electromagnet 813.

[0053] The implementation principle of the present invention is:

[0054] In the initial state, the fixed contact 4 is fixed in the mounting slot 807, and the moving contact 6 is disconnected from the fixed contact 4, that is, the thermostat is in the disconnected state. If you need to connect the circuit, refer to Figure 9 , electromagnet 813 is energized, electromagnet 813 attracts permanent magnet 819 on cylinder 816, so that permanent magnet 819 fits electromagnet 813, roller 818 and plunger 817 are pressed into cylinder 816, see Figure 8 At this point, permanent magnet 819 drives air cylinder 816 into rotating sleeve 814. Simultaneously, air cylinder 816 drives pressure block 815 to press against the outer wall of turntable 802, securing slider 805 to turntable 802. As stepper motor 803 rotates turntable 802 via belt 804, turntable 802 drives slider 805 to rotate synchronously. Slider 805 drives insulating rod 810, pushing movable contact 6 into contact with fixed contact 4, thus connecting the thermostat.

[0055] The present invention monitors the circuit temperature in real time through the temperature panel on the integrated top box 2. If the circuit temperature rises suddenly, it can be determined that the appliance is short-circuited; if the circuit temperature rises slowly, it can be determined that the appliance is overloaded.

[0056] When the appliance is overloaded, the stepper motor 803 drives the turntable 802 and the slider 805 to rotate through the belt 804, so that the insulating rod 810 disengages the moving contact 6, and the moving contact 6 is disconnected from the fixed contact 4 under the action of the spring 7; when the line temperature drops, the controller on the integrated top box 2 controls the stepper motor 803 to operate, so that the stepper motor 803 drives the turntable 802 and the slider 805 to rotate through the belt 804, so that the slider 805 drives the insulating rod 810 to push the moving contact 6 to connect with the fixed contact 4, so that the temperature controller is connected.

[0057] When the electrical appliance is short-circuited, the stepper motor 803 drives the turntable 802 and the slider 805 to rotate through the belt 804, causing the insulating rod 810 to disengage from the moving contact 6, and the moving contact 6 is disconnected from the fixed contact 4 under the action of the spring 7. Then the electromagnet 813 is energized in the reverse direction, causing the electromagnet 813 to repel the permanent magnet 819 on the air cylinder 816. At this time, the air cylinder 816 drives the pressure block 815 away from the outer wall of the turntable 802, so that the slider 805 is separated from the turntable 802; when the line temperature drops, the stepper motor 803 drives the turntable 802 to rotate through the belt 804. Since the slider 805 is separated from the turntable 802, during the rotation of the turntable 802, the turntable 802 cannot drive the insulating rod 810 to close the moving contact 6 and the fixed contact 4 through the slider 805, so that the thermostat is in the disconnected state, avoiding the thermostat automatically connecting after the temperature drops, causing secondary damage to the electrical appliance.

[0058] Specifically, in the present invention, when the electrical appliance is short-circuited, the slider 805 separates from the turntable 802, and at the same time, the air hole of the air cylinder 816 faces the fixed contact 4 and the moving contact 6. At this time, when the stepper motor 803 drives the turntable 802 to rotate through the belt 804, the convex platform 812 on the turntable 802 will continuously press the roller 818, so that the roller 818 drives the plunger 817 to push back and forth into the air cylinder 816, blowing the gas inside the air cylinder 816 toward the fixed contact 4 and the moving contact 6, accelerating the lowering of the fixed contact 4 and the moving contact 6, and preventing the short-circuit high temperature of the fixed contact 4 and the moving contact 6 from being transmitted to the internal components of the fixed terminal 9 and the moving terminal 5, causing damage to the internal electrical components and circuit boards of the fixed terminal 9 and the moving terminal 5.

[0059] Another embodiment addresses the problems existing in the prior art;

[0060] Problem 1: Communication protocol wiring is complex, making it impossible to achieve high- and low-voltage isolation (compared to CN102387059A's reliance on terminal resistors). While existing industrial bus technology simplifies network deployment, its physical layer design is still limited to a fixed topology, making it difficult to adapt to the dynamic networking needs of multiple nodes. Particularly in high-density industrial scenarios, traditional protocols (such as CAN and Modbus) rely on complex wiring to achieve high- and low-voltage isolation, resulting in skyrocketing cable costs and insufficient anti-interference capabilities. Furthermore, existing communication solutions generally lack data encryption mechanisms, making sensitive information (such as temperature and current parameters) susceptible to interception or tampering during transmission, making it difficult to meet the stringent information security requirements of the intelligent manufacturing sector.

[0061] Problem 2: The temperature and current protection functions are separated, lacking integrated monitoring (compared to the protection function limitations of CN106527522A). Current thermostats with integrated protection functions mostly use a static threshold judgment mechanism, and their current and voltage monitoring modules usually trigger protection actions based on fixed thresholds. However, the operating conditions of industrial equipment are complex and changeable, and overloads or short circuits may exhibit transient or gradual characteristics. Static thresholds are difficult to dynamically adapt to actual load changes, which can easily lead to misjudgments or missed judgments. For example, in the legal inrush current scenario at the moment of motor startup, traditional solutions may mistakenly trigger protection due to the rigid threshold, resulting in production interruption; in the gradual overload scenario, the risk may not be avoided in time due to response delays.

[0062] The present invention proposes the HaiNet bus communication protocol, which implements multi-node dynamic networking and data encryption transmission based on network cables, specifically including:

[0063] Innovation at the protocol layer: Dynamic topology management: Using a lightweight networking algorithm based on a token ring, nodes automatically identify network topology by broadcasting heartbeat packets (interval ≤ 100ms), supporting seamless switching among star, bus, and hybrid structures.

[0064] Hardware layer optimization: Integrated high and low voltage isolation modules (withstand voltage ≥ 2500V) and a hybrid design of optical coupling and magnetic coupling enable co-linear transmission of 24V control signals and 380V power electricity in a single network cable, reducing wiring costs by 70%.

[0065] Compared with the existing technology; compared with the terminal resistance automatic matching solution of CN102387059A, the HaiNet protocol of the present invention abandons the dependence on the physical layer. Through the dynamic networking and encryption mechanism of the logical layer, the measured bit error rate in a 10-node network is ≤0.001%, and it is compatible with Modbus-TCP devices, which significantly improves deployment flexibility.

[0066] This invention designs a temperature-current-voltage coupled protection model, which achieves precise protection through multi-source data fusion and dynamic threshold adjustment:

[0067] Dynamic threshold calculation: Overcurrent protection: The protection threshold is dynamically adjusted based on the load characteristic curve fitted based on historical current data (sampling rate 1kHz) and the real-time temperature (for example, the current threshold is lowered by 20% above 40°C) to prevent false triggering of motor startup inrush current.

[0068] Overvoltage protection: Using a sliding window algorithm (window width 500ms), it provides early warning when identifying voltage fluctuation trends (e.g., rising slope > 5V / s for five consecutive cycles), with a response speed of ≤10ms.

[0069] Tiered response strategy: Level 1 response (overload): Trigger audible and visual alarms, log the fault, and maintain circuit connectivity. Level 2 response (short circuit / overvoltage): Immediately disconnect the main circuit, activate the 816 air pump for cooling, and push the fault code to the cloud via the HaiNet protocol.

[0070] The advantages of this invention are: First, the short-circuit isolation reliability is increased to 99.9%, and the contact cool-down time is shortened to 8 seconds (compared to 30 seconds with traditional solutions). Second, the communication bit error rate is ≤ 0.001% (compared to 0.1% with traditional solutions), and it supports 32-node networking. Third, the protection response speed is ≤ 10ms (compared to 50ms with traditional solutions).

[0071] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and modifications fall within the scope of the invention as claimed.
